WebThe proposed model was compared with PCA-MLR, MARS, and PCA-MARS downscaling methods. Eight general circulation models (GCMs) were considered, out of which only CAN-ESM2 (second-generation Canadian Earth System Model) GCM was found suitable for the study area.

Web14 jun. 2024 · A multi-linear regression ( MLR) approach combining previous lab data and the current data was used to identify the relative importance of individual water chemistry components in predicting acute Pb toxicity for both species. As anticipated, the P. promelas best-fit MLR model combined DOC, calcium and pH. WebThe first step is to perform Principal Components Analysis on X, using the pca function, and retaining two principal components. PCR is then just a linear regression of the response variable on those two components.
